Local Environmental Conditions
Most of the area around the center of Rouyn-Noranda is built-up land, with some woodland. Of the trees nearby, poplar is the one that matters most for allergies. There is plenty of grass pollen here too. In the immediate area, planted trees and mown lawns are the main sources in the built-up parts.
Poplar leads the season in mid-spring, bringing the main tree pollen peak. Grasses take over in early summer, with temperatures around 15°C, and their pollen lingers into late summer. Weeds on open ground add a smaller late peak from midsummer into mid-fall. By mid-fall, as temperatures fall to around 10°C, pollen levels are low again.

Does pollen in Rouyn-Noranda come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Rouyn-Noranda based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Rouyn-Noranda, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.

Understanding the Scale
The 0–100 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
